Summary
Japan launched the world’s first wooden satellite, LignoSat, to test if wood can function as a space-grade material. Developed by Kyoto University, the satellite is made of honoki wood, chosen after a 10-month ISS experiment proved its suitability for space.
Designed without screws or glue, LignoSat will orbit Earth for six months, enduring extreme temperature swings and measuring wood’s resistance to space radiation. Advocates highlight wood’s eco-friendly re-entry properties compared to metal.
Researchers envision wooden structures for future space habitats, potentially boosting the timber industry.
We can’t let Japan get ahead of America on this! NASA, send your finest recruiters to Pennsylvania right now and find the most capable Amish!
We need to send them into low earth orbit in a horse drawn spacecraft!
Stop trying to normalize Amish. They are unethical as fuck and have child labor in dangerous unpaid conditions.
I am sorry your people do not have the concept of humor, but I hope it does come to your planet someday.
However, it only survives in space for 22 minutes, but then it resets to its origin so no biggie.

Edit well I’d never heard of honoki wood! Learn something new every day. Honoki (朴の木, hou wood, Japanese Bigleaf Magnolia, Magnolia obavata
-hinoki wood, from Chamaecyparis obtusa.iirc wood was used by the chinese for their heat shield’s ablator or something?
All Hearthian interlopers would be proud.
A treehouse in space is all my inner child has ever wanted.
Strong Outer Wilds vibes :) :)
Stone age Thag would be proud…
Thag not make moving star from wood! Wood weak! Only good for spear shaft! Thag make moving star from flint!
I’m curious how much the wood will expand and contract each hour going through the extreme heat and cold constantly.
I’m guessing they freeze-dried it already, so not that much.
If they didn’t, it will freeze-dry itself. I have no clue what that would do to the dimensions, since it’s not going to be a controlled process like it would be on Earth,
This is why I’m curious:
It will measure how wood endures the extreme environment of space, where temperatures fluctuate from -100 to 100 degrees Celsius (-148 to 212 degrees Fahrenheit) every 45 minutes as objects orbit through darkness and sunlight.
I’ve never heard of anyone freeze-drying an instrument. Space doesn’t freeze things, that requires somewhere for the heat to go. That’s an interesting idea though.
Maybe it won’t expand and contract for the same reasons. After all, there isn’t any moisture in space.
Cooling by radiation is slower than convection or conduction, but it still happens. The James Webb went from room temperature to deep cryogenic in a few months, and it’s big. As for moisture, things cook off into a vacuum very easily. That’s the foundational to the whole concept of freeze drying, actually.
Freeze dried wood is absolutely commercially available, if pricey. I have no idea if anyone has used it for musical purposes either. There’s a lot of audiophile-ish magical thinking in that space so it’s possible nobody has bothered.
Edit: Although, since this is a research project, maybe not freeze drying it first was the point.
Pretty cool info. Thank you
Well, as long as they forgo on the principle of Wabi-sabi as we do not need that mindset in space and your life depends on it.
